Find the length of an iterable.

Similar: index, indexRange, size, isEmpty.


function length(x, i, I) // x: an iterable // i: start index [0] // I: end index [END]
const xiterable = require('extra-iterable'); var x = [2, 4, 6, 8]; xiterable.length(x); // → 4 xiterable.length(x, 1); // → 3 xiterable.length(x, 1, 3); // → 2
